Sure, but let's look beyond device detection. For instance, it does not

communication with a virtual device, once detected.
This is true, of course. However, there are going to be a set of
virtual devices which don't necessarily have to have super-high
performance. In the case of a hwrng device, even doing DMA is probably
overkill.
Outside of pci_device_id driver matching, is there much value here?
If we can get a set of device drivers that if not all then at least a
number of hypervisors and/or emulators can agree upon, I think that's
much won.
